Hi rootsnarms
I would like to join
pilate in welcoming you here
Based on your description of your sister, she does seem a difficult person to get along with. Her behavior at and after your wedding is quite disturbing. I can imagine this also shocked your husband, how does he feel about the situation with your sister?
When I look at your sister, she seems to be engaging in a lot of '
projection' and '
splitting', classic BPD behaviors. Her words and actions are quite unpleasant, yet most likely are only a reflection of her own inner turmoil and negativity which she is projecting onto you.
In your sister's mind her own behavior might make perfect sense, even the extreme splitting into 'all-good' and 'all-bad' categories. If she has BPD, she most likely has distorted thinking patterns though she herself might not even realize her thinking is distorted.
You are struggling with her behavior and negativity which is understandable. Verbal abuse and false accusations are very unpleasant and can be quite tough to deal with. Perhaps things will change in the future. Perhaps your sister will at some point realize there is something wrong with her behavior and seek help. Whether she does or not, is out of your control but what you can control is your own behavior. Setting and enforcing/defending firm boundaries is very important when dealing with a BPD family-member. Boundaries help to keep us safe and preserve our own well-being.
Thanks for sharing your story with us
